Trend lines are the most effective primary drawing tools for technical analysts in any financial market to depict and measure trends.
Similar to horizontal support and resistance lines, trend lines are also drawn by connecting highs and lows. However in case of trend lines, you need to connect the dynamic highs and lows as the trend progresses.
Trend lines are always to be redrawn if price accelerates in the direction of trend.
In this article, we will discuss how to draw up-trend and down-trend lines, and when horizontal trend lines are drawn to identify support and resistance levels.
How to draw trend lines
In a rising market, a trend line is a straight line drawn by connecting a series of ascending bottoms. It’s called up-trend lines.
Likewise, in a falling market, a trendline is a straight line connecting a series of peaks. It’s called down trend lines.
In order to consider a trend line as a significant trend line, it must connect two or more peaks or troughs. If it only touches one point, it cannot be considered as a true trend line.
Some technical analysts prefer three touches as minimum to consider it as a significant trend line. There are no specific rules defined for this, it depends on the trader.
The up-trend or down-trend line derives its authority from the number of times it has been touched, i.e. the larger the number, the greater the significance. Remember, if the price approaches the line, it’s almost as important as an actual touching.
Here is the diagram showing how down-trend line is drawn in a falling market.
In a down-trend, trend lines are drawn by connecting at least two highs or three highs with a line.
In an uptrend, a trend line is drawn by connecting at least two or three lows with a line.
The more time prices touch the trend line, the more valid it is.
Here is how the up-trend line is drawn in a rising market.
Trend line breaks are watched very closely by technical traders.
In an uptrend, when the uptrend support trend line breaks, a possible reversal may begin. Before the reversal, price might consolidate for sometime or even break above the trend line again before a downtrend.
Trend lines are drawn to identify current trends, or to help you confirm a reversal of the current trend.
If the prices are under a trend line, the overall direction of the trend is down. If the prices are above the trend line, the overall direction is up. When price breaks through the trend line, it’s likely that prices will reverse direction.
While drawing trend lines, few traders prefer to connect the candlestick bodies while others try to connect the wicks/shadows of the candle. There is no right or wrong method, it depends what works for you.
You can draw trend lines mentally by eyeing the chart or physically, by drawing the line with your trend line charting tool.
In a rising market, the uptrend line acts as a support and in a falling market, the downtrend line acts as a resistance.
Trend line shows the direction where the stock’s current trend is expected to go. It creates a boundary to know when the trend is getting over.
Many traders also use channel lines to analyse how a stock moves. Channel lines are parallel lines drawn along the tops of uptrend price patterns, and along the bottom of downtrend price patterns. These lines are also used as profit taking points.
When price penetrates the rising trendline and closes below it, then that is an indication to change in trend.
An up-trend line is officially not considered as broken until a previous low is surpassed. Likewise, a down-trend line is considered to be broken when the previous high is surpassed.
A break above the declining trendline is bullish, while a break below the advancing trend line is bearish.
Horizontal trend line
In a sideways market, trend lines can be drawn horizontally connecting the upper and lower boundaries of the trading range.
In the head-and-shoulders price pattern, the neckline drawn connecting low points of the head and shoulders is also known as horizontal trend lines. Penetration of price below or above these horizontal line signals possible trend reversal.
Penetration of a trend line can signify either:
- a reversal in the previous trend, or
- a continuation of the present trend after consolidating for sometime.
After consolidation, it might continue the present trend or reverse.
In other words, at the point of violation, the odds strongly favour a change in trend. Such change in trend can be a reversal or consolidation before resumption in trend or reversal. No one knows which possibility will prove to be the outcome.
Trend lines are the easiest technical tool to identify trend and reversal. It requires practice and experimentation to master such an art.
In addition to trend line break or reversal, technical analysts prefer to refer to other technical tools for confirmation.
